Abstract

In a group of 50 workers of a storage battery plant analysis was made of the δ-amino-Ievulinic acid (δ-ALA) in a single urine specimen .taken before and after work. The results were compared with the δ-ALA concentration in a 24-hour specimen. The δ-ALA concentrations in the single urine specimen were either higher or lower than the concentrations in the 24-hour specimen. Statistical analysis however showed a good correlation between these two values (r-before work = 0,65, r-after work = 0,73). In view of this, the δ-ALA determination in the single urine specimen is acceptable for field practice.
